As the name implies, the Rock Restaurant and bar is perched on a rock — one that can be found in the middle of the Indian Ocean. Once a fisherman's post in Zanzibar, you can now get there using its dedicated boat service, or wait for low tide and wade over.

Instead of swinging from the chandeliers, drink inside one.

Rated the best bar in the world by the World's 50 Best Bars, Artesian in London changes its cocktail menu every year. This year, the bar's theme is "surrealism," and it is serving drinks in surreal objects like giant metal ant sculptures, fur cups, and lego elephants.

Harry's Bar in Venice is about as iconic as the people who have imbibed here — Charlie Chaplin, Orson Welles, and Truman Capote, to name a few, as well as a roster of European kings and queens. But that's not why it's iconic: Its real claim to fame is being the birthplace of the Bellini (white peach juice and prosecco) as well as the inventor of carpaccio.

What’s better than a drink with a view? A drink with a view of monkeys, as is the case at the Berlin's 25hrs Bikini Hotel's rooftop bar, the Monkey Bar, which looks right into the Berlin zoo's monkey enclosure and features floor-to-ceiling windows for panoramic views of the primates. The cocktail menu is, appropriately, tiki-leaning.

It's not surprising that a cocktail bar opened by Grant Achatz, arguably one of the world's best chefs, would be the bar to raise the bar. Drinks at Chicago's The Aviary are outrageous molecular concoctions that are essentially pieces of art: there are 25 kinds of ice, and cocktails are often brewed table side and usually served in fascinating vessels, like inside a ball of ice that needs to be smashed or in beakers heated by bunsen burners.

Consistently ranked one of the best cocktail bars in the world, as well as the best bar in America, The Dead Rabbit in New York's Financial District is home to 145 types of Irish whiskey, making it the largest collection of Irish whiskey in America, and possibly the second largest in the world.

While Sean's Bar is not much to look at now, you can drink in some bragging rights at this tiny tavern in Athlone, Ireland.

To put it into perspective, that is is 200 years before the First Crusade, and the year Vikings discovered Greenland.

Hipster even for Portland standards (and not surprisingly attached to Portland's Ace Hotel), Clyde Common features farm-to-table cooking, communal tables, and killer cocktails like the Bourbon Renewal (bourbon, lemon, crème de cassis, bitters).

The Roaring '20s are alive and well at London's Nightjar, a speakeasy that features Prohibition-era drinks, live jazz and blues music, and old-school glamour in spades.

In typically modest Japanese fashion, one of the world's best bars is as understated as they come.

There is no menu at this 18-seat bar.

La Bodeguita del Medio in Havana, Cuba, claims to have invented the mojito. Whether that's true or not, its mojito has Ernest Hemingway's stamp of approval, as a scribble of his on the wall reads "My mojito in La Bodeguita, my daiquiri in El Floridita."

The Soggy Dollar bar in the British Virgin Islands invented the Painkiller cocktail. What pain on this beautiful island could have led to the name of the drink is unknown, but the bar is named for the fact that there's no dock. In other words, your dollars might get soggy.

It may not be the most stylish bar in the world, or have the latest sound system, or flashy mixologists, but Denver's El Chapultepec makes this list for good reason. Formerly a Mexican Cantina, it still serves up mean Mexican food, alongside cool jazz tunes almost nightly. Open since 1933, "the Pec" was a Jack Kerouac favorite and a popular stop for the music legends Ella Fitzgerald, Frank Sinatra, and Duke Ellington. Apparently, even Bill Clinton picked up his sax and laid down some tunes here.
